Southern Pacific Rail Road worker's. About to be shipped to Ohio, to a new owner. Has a fresh battery, hums like an accutron! Was originally a little slow, and a quick adjustment now its on time like a quartz! 10K RGP, hope this guy has a new strap because although the original is included with the cool clasp which is also gold, it is almost 40 years old! Cleaned up really nice, not a scratch. 2181 w/ hack movement. Bye bye!
